MICROWAVE-RADIATION SYNTHESIS OF FAST ION IC CONDUCTOR NA5YSI4O12

Single phase Na5YSi4O12 which is difficult to be prepared by conventio nal solid state reaction, was synthesized by microwave radiation synth esis method, The relationship between synthesis conditions and the pha ses in products was discussed, A comparison was made of the properties of samples prepared by Sol-Gel method with those by microwave radiati on synthesis method, respectively, Compared to conventional Sol-Gel me thod, the experimental procedure was much simplified and reaction time was shortened when Na5YSi4O12 was prepared by microwave radiation syn thesis method, The sample prepared by microwave method has a particula r micro-structure, aggregating state and defect structures, which lead s to the decrease of ionic conducting activation energy.
